I'll say one thing that I didn't like with my cylinders. Jorge had the Machinst trim my fins. I did not instruct Jorge to trim my fines

You did say fix the cyl's so their usable, since you were not taking them back to the machinist who screwed them up to begin with, and the fins had to be cut in order for you to use them.


If you had tried to mock up the cyl's with the studs you would have found the problem. Jorge had asked me to mock them up on my case to check for any issues with mounting and becase my case was cut for 103mm cyl's and it had the long stroker studs installed.


There are a left & right cyl, the left cyl fit no. 2 & no. 3 cyl position, the right cyl will fit the no. 1 & 4 cyl position in the case, that is partially because of the where the fins are cut so they can sit next to each other and the other side where the notch is to clear the case, then there is also because of the well know fact that the Type lV has the off set stud pattern of which the bottom 2 studs are wider than they are at the top, which means the cyl's can not be fliped upside down .

Your machinist that had drilled the stud holes and trimmed the cyl's for clearance made you 4 left cyl's, and the only fix was to machine all the cyl fins the same so they would fit the stud pattern and have the capacity to cool the same.

I have not fitted the cylinders with studs. Since I have not done this yet, I may stand corrected. I received the stud pattern from Gregg Riddle, and had a blue print made in order for a CNC progarmmer to input. If what you say is correct, I will need to have a mechine shop do 8 more sets (bummer). I will get some ARP bolts and go to the next level.

Richard, you once gave me a name of a rebuilder of speed-o and tach. I tried to find the contact again but don't remember the name. He makes custom gauge face plates. Do you still have or remember his name or site?

The stud pattern was correct, but what has to be done is the fin designed has to be mirrored, and what happen was the fin design was mirrored which is shown buy your pics with them installed in the case and so was the stud pattern but shouldn't of been. So the fins get mirrored and the stud pattern does not, to get a better idea what I am talking about check against a set of stock cyl's

What do you mean about doing 8 more sets ?


This place does good work.

Richard, am I to understand the new 39 gram 356 styled lifter won't be able to withstand the spring rate?

For the money you have in this motor, it's not worth even taking a chance. I have a set of the E Plus 356 Style lifters & the New design Aluminum bushings, and I will run 110 pds seat & it will be 270 pds over the nose with Beehive springs but I am running N/A. You should have at the very least 170 pds seat and at least 350 pds over the nose and those lifters are not going to handle those pressures very long especially when the turbo spools and the rpms jump.

The Tool Steel Type 1 are much stronger, and better than that would be to go roller...

But it's your decision.

Is there any copmany state side selling tool steel lifters?



All of my gauges are in good working order. I need custom face plates, I bought some dual cht/egt gauges and I would like to have everything uniform, it possible.

If you would of search their site, you would of found they do custom face plates.
